Title: Audio-frequency amplifier/low-frequency amplifier
Inventor: SAKANO HIDEKI
IPC: H03F1/34
Filed: 1981-01-31
Abstract: A low-frequency amplifier has positive feedback for compensating for the nonlinearity in the impedance of the load. Such a low-frequency amplifier is to be provided with a circuit which automatically compensates for an opposing electromotive force generated by a connected load and which prevents both the amplifier and the load from being damaged in the case of extreme voltages occurring due to mismatching. It is proposed that the low-frequency amplifier exhibits a protective device (see Figure 2) which should prevent damage to the low-frequency amplifier or to the load due to any overvoltages occurring, and that the protective device consists of a switch arranged in the feedback branch and of a controller which monitors the input voltage of the feedback branch and always opens the switch and holds it in the open condition when the input voltage of the feedback branch exceeds a predetermined nominal value. <IMAGE>

Title: Air quantity regulator for vapour extractor hoods, vacuum cleaners, air-conditioning devices or the like
Inventor: TRITT GERHARD
IPC: F24F11/76
Filed: 1981-10-17
Abstract: The invention relates to an air quantity regulator for vapour extractor hoods, vacuum cleaners, air-conditioning devices or the like, having a desired-value adjuster which changes the speed of the fan motor. In known devices of this type, the speed can be adjusted independently of the quantity of air actually conveyed, with the result that changing flow conditions, such as filters becoming blocked, are not taken into consideration. It is proposed according to the invention to arrange an indirectly heated temperature sensor (3, 24) in the fan air flow (23), the output signal of which temperature sensor is fed to a control circuit (12, 38) which changes the speed of the fan motor (7, 19) as a function of the difference from the desired value of the connected desired-value adjuster (10, 27). The indirectly heatable temperature sensor is cooled as a function of the air quantity conveyed so that its output signal is a direct measure of the air quantity conveyed. Depending on this output signal, regulation is now possible in accordance with the air quantity actually conveyed. A second temperature sensor (4, 25), which is connected to the control circuit (12, 28), is advantageously arranged in the fan air flow for temperature compensation. The output signal of the second temperature sensor (4, 25) can thus be selected as a zero or reference potential so that the control circuit operates independently of the temperature of the air to be conveyed. <IMAGE>

Title: Device for surface treatment of film-like materials using corona discharges
Inventor: KALWAR KLAUS
IPC: B29C59/10
Filed: 1981-11-26
Abstract: The device for surface treatment of film-like (sheet-like) materials using corona discharges has a generator which produces a high-frequency high voltage, and has a pair of electrodes between which the film-like material is passed at a predetermined speed (weight). The pair of electrodes consists of a base electrode (which is preferably constructed as an electrode roller and on which the film-like material is supported) and an opposing electrode (which is provided with a row of discharge tips and is designed in the form of a plate in outline). This opposing electrode can have allocated to it further opposing electrodes, as subsequent electrodes, which are constructed in the form of blades or rollers. The electrical initial treatment of the film-like material is carried out by means of the electrode which is equipped with discharge tips and to which less electrical energy can be made available than the subsequent electrodes. As a result of the opposing electrode which is equipped with discharge tips, adhesion centres are produced on the film-like material, which adhesion centres are located close to one another, are distributed uniformly, and on which the corona discharges of the subsequent electrode or of the subsequent electrodes are oriented, resulting in treatment which covers the surface.

Title: Static network coupling for high power for coupling a three-phase network at a higher frequency and a single-phase network at a lower frequency
Inventor: BECK HANS-PETER DR ING
IPC: H02J3/34
Filed: 1981-12-17
Abstract: A static network coupling for high power for coupling a three-phase network at a higher frequency and a single-phase network at a lower frequency, having a frequency-reducing direct converter, which is connected to the three-phase network, with a three-phase output in which two phase outputs are connected to the single-phase network and, in each case via an electronic phase-shifter for balancing the load, to the third phase output, and having an electronic phase shifter which is arranged between the phase outputs connected to the single-phase network and has parallel capacitance for the entire single-phase reactive power, the object exists to achieve a supply of energy back from the single-phase network into the three-phase network as well, without any special increased circuitry cost. This is achieved in that the phase reversal required to supply electrical energy back from the single-phase network is always carried out electronically by changing over the delay angle of the direct converter. A particular field of application is railway power supplies.

Title: Method for frequency-demodulation and FM demodulator
Inventor: HANSEN JENS DIPL ING
IPC: H03K9/06
Filed: 1982-04-01
Abstract: A method is proposed which is used for frequency demodulation. According to the method, from a first squarewave-shaped frequency-modulated pulse sequence (I1), a second pulse sequence (I2), which is inverse to the first pulse sequence, with constant interpulse intervals (p10, p11,...) is formed. The interpulse intervals are shorter than the shortest pulse of the first pulse sequence to be expected. From one pulse each of the first pulse sequence and one associated interpulse interval each of the second pulse sequence (I2), a third squarewave-shaped pulse sequence (I3) is formed, the pulses of which have a duration ( DELTA t1,  DELTA t2,...) which corresponds to the time difference between a pulse of the first pulse sequence and the associated interpulse interval of the second pulse sequence. From the third pulse sequence, a fourth triangular pulse sequence (I4) is formed by integration and from this pulse sequence the modulation of the first pulse sequence is recovered by amplitude demodulation. <IMAGE>
